Cartridge filters can be a cost effective way to remove sediment, odour and colour from your rainwater. At Kingspan Water, we stock a large range of filters and replacement cartridges.
Cartridge filters in a variety of sizes and grades are available. For general rainwater filtration for internal appliances, such as a washing machine, a coarse cartridge such as a 50-micron pleated cartridge is sufficient.
For pre-filtration before using a UV disinfection system, two-stage filtration is required. A 20-micron primary filter traps solid particles, and a 1-micron secondary filter will trap microorganisms.
